Use of moored floating structures, such as SPARS and FPSOs, as production and/or storage systems is now ever-increasing practice in offshore oil and gas industry, particularly with the operation moving to deep sea in the new century. Operating in such an environment, the structures are likely to expose to the very hash seas and extremely steep waves because they have to remain on sites even when encountering severe weather. Such a situation implies that the vessels of this kind may not avoid undergoing large motions and large loading, which will result in many undesired consequences, such as disturbing the operation of facilities on board, increasing the risk for the system to be damaged and so on. Much previous work has suggested that the interaction between moored floating structures and extremely steep waves need to be addressed with great care and has identified that fully nonlinear analysis is necessary to deal with it. However, there are many challenges associated with the analysis in the framework c fully nonlinear theory, such as dealing with the continuous change in complex oomputional domain and the over distoration of elements caused by larg motion of the structures. The purpose of this project is to develop a numerical technology, with which the complex problem can be solved with satisfactory efficiency and accuracy. The developernent of this project will help to improve the safety and reliability of moored floating vessels during design and operation.
